为1个网站的2个不同部分设置2个不同的自定义错误页面

Question

Currently I'm having 1 custom error page for my whole ASP .NET site:

<system.web>
    <customErrors mode="RemoteOnly" defaultRedirect="~/ErrorPage.aspx" />
</system.web>

However, I would like to set up 2 different error pages, so that error on different part of the side will cause redirection to different error pages. For example:

• When users encounter an error in a page within http://example.com/Part1/ they will be redirect to ErrorPage1.aspx .
• When users encounter an error in a page within http://example.com/Part2/ they will be redirect to ErrorPage2.aspx

Is it possible at all?

Answer 1

ASP.NET allows certain settings within web.config to be overridden in subdirectories; this includes the error handling. Simply create:

<system.web>
    <customErrors mode="RemoteOnly" defaultRedirect="~/ErrorPage1.aspx" />
</system.web>

as Part1\\web.config , and

<system.web>
    <customErrors mode="RemoteOnly" defaultRedirect="~/ErrorPage2.aspx" />
</system.web>

as Part2\\web.config .

No, the page shown can only be based on the HTTP result code, like 500, 404, etc. as can be read on this page . Quoted from there:

"A better approach is to use a custom error page, which entails creating and designing the custom error page and specifying its URL in the section's defaultRedirect attribute. You can even have multiple custom error pages for different HTTP error statuses."

You could use your own errorhandling in try/catch blocks and do the redirects manually there.
